ED power take-off activation
Function
More information on how power take-offs can be combined is found in the document Power take-off combinations under Power take-offs and hydraulics.

FunctionThe function is intended to activate the power take-off from the driver area and from outside the cab. The power take-off is controlled by the BCI control unit. An ED power take-off cannot be engaged and disengaged like other power take-offs.

If a hydraulic pump is connected to the power take-off, this control can, for example, be used to control a bypass valve to pressurise the hydraulic system if required.

Changes to adjustable parameters are done using SDP3 (Scania Diagnos & Programmer 3).

For Euro 6, the silencer is automatically regenerated. When this occurs, the vehicle’s control units regulate the speed and power, which affects the power take-off. In those cases where the drive from the power take-off must have a stable speed, the connec-tion must be done via preparation from Scania or via connection to the BCI control unit.

ED power take-off activationFunction

ActivationThere are different conditions to activate the power take-off. Depending on the pow-er take-off type there may be permanent activation conditions and selectable activa-tion conditions. The selectable activation conditions’ parameters can be set as required for the particular installation. The activation conditions are there to protect the bodywork equipment.

If all activation conditions are fulfilled, the function can be activated via BIC (Bod-ywork Interface Configuration) and External CAN.

The switch must be of the 2-position switch type.

Permanent activation conditions• No permanent activation conditions.

Selectable activation conditions• Applied parking brake conditions

If the vehicle is equipped with BCI functionality, then the following activation con-ditions can also be used.

• Neutral position conditions

• Reverse gear conditions

• Upper engine speed limit for activation

• Lower engine speed limit for activation

• Upper vehicle speed limit for activation

• Lower vehicle speed limit for activation

Activation settingsThere are 3 different activation settings.1

• Manual

• Automatic

• Drive position

ManualFor activation using the Manual setting, all the activation conditions must be fulfilled before the power take-off can be activated with the switch. If the switch is activated when the activation conditions are fulfilled, the power take-off is not activated. De-activate and activate the switch again to activate the power take-off.

AutomaticFor activation using the Automatic setting, activation can take place using the switch before other activation conditions are fulfilled. The voltage must be on before the switch is switched on, otherwise the switch must be switched off and then be reacti-vated. The power take-off is activated when all activation conditions are fulfilled.

Drive positionWhen activating with the Drive position setting, the same preconditions apply as for Automatic activation, although the voltage does not need to be switched on before the power switch.

1. BCI functionality is required to change the settings. Activation with the Manual setting is standard from the factory.



DeactivationMake the deactivation request by interrupting the activating input signal from the switch or via an External CAN request. The power take-off is automatically disen-gaged as soon as one of the deactivation conditions is fulfilled.

Selectable deactivation conditions• Parking brake conditions

If the vehicle is equipped with BCI functionality, then the following deactivation conditions can also be used.

• Neutral position conditions

• Reverse gear conditions

• Upper engine speed limit for deactivation

• Lower engine speed limit for deactivation

• Upper vehicle speed limit for deactivation

• Lower vehicle speed limit for deactivation

Acknowledgement for activation of power take-off in instrument cluster

MiscellaneousInformation that the power take-off is activated is sent to other control units and is also displayed in the instrument cluster.

AcknowledgementThe driver receives an acknowledgement that one of the power take-offs is activated when the indicator lamp in the instrument cluster comes on. The indicator lamp is not unique and is used by all power take-offs in the vehicle. The driver can therefore not determine which power take-off is active.

If the vehicle has BCI functionality, it is possible to use status and warning lamps 2, 8, 9 and 10 to indicate to the driver which of the power take-offs is activated. The indicator lamp is set with parameter in SDP3.

Each power take-off has a unique acknowledgement signal which is sent to other sys-tems in the vehicle when they need to know if and which power take-off is activated.

Power take-off without acknowledgement sensorIf the power take-off does not have an acknowledgement sensor, the acknowledge-ment signal is created internally in the BCI control unit and it tracks the status of the activating output signal of the power take-off’s solenoid valve.

Cylinder balancingThe cylinder balancing function governs the quantity of fuel injected into each cyl-inder to reduce engine vibrations at low engine speeds. In certain cases, the load in combination with cylinder balancing can cause engine vibration to intensify. In these cases, the function can be deactivated with the Cylinder balancing parameter in SDP3.

Retrofitting control unitsIf a power take-off is retrofitted, the BCI control unit must be installed and the SOPS file (Scania On-board Product Specification) be updated. If the vehicle does not have a BCI control unit, it can be retrofitted. Contact a Scania workshop for assistance with retrofitting a BCI control unit.



Double ED power take-offsThe vehicle must either be ordered with an ED power take-off with 2 electrical con-nections from the factory or the control units must be reprogrammed via an update of SOPS during retrofitting.

Request

Connecting and activating a functionThe installation of the ED power take-off is carried out by the bodybuilder.

If necessary, an acknowledgement sensor can be fitted on the bodywork. The sensor is then connected to the acknowledgement signal in the BCI control unit and controls the indication in the instrument cluster. The installation is carried out by the body-builder.

The connection examples below only describe connection with acknowledgement sensor.

Electrical preparation from the factoryTo facilitate the installation of power take-offs there are electrical preparations for power take-offs, refer to preparations from the factory under chassis conditions.

The electrical preparations include power take-off control in the BCI control unit and cable harness from the cab to the frame. The cable harness is fitted at the factory and allows the bodywork to be connected directly to a connector on the frame.

Part information and connection positions

Connectors V122 (ED1) and V150 (ED2) are placed inside the left-hand frame mem-ber.

Information on how the power take-off is connected to C259 is found in the docu-ment Combinations of power take-offs under Power take-offs and hydraulics.
